How to use this page

This page has all the subject content that you will need to complete the required study for IST. You will find a range of activities called “portfolio”, “essential tasks” and ” weekly homework”. You are required to complete all of these tasks as they all make up a component of your assessment schedule. You are also expected to present your completed work on a Googlesite sharing this site with your teacher.

There are due dates displayed with each task. The Portfolio tasks will achieve a mark full marks for a well completed task, half marks for a incomplete but mostly completed and a zero mark will be given for a non attempt.The Assessments details may be found here.

Your work will be completed within the Cloudshare environment, however, an important security issue exists and you are required to ONLY use your school credentials for all online use within Cloudshare or external for example Voki.

The series of YouTubes are important to view as these will present to you visual detail that you may not see in the text. The scheduled IST end of Semester Examinations will be created from the content found on this site.

essential task 1
a) Create your own website using Cloudshare sites by visiting here. use your first name and initial of your family name so that others in the course will have a standard format to find your website. Never place any personal details on your website.

b) Share as an owner your website with your IST class teacher first.name@syd.catholic.edu.au . This is a CEO policy for student websites.

Introduction

Since early times people have communicated. This communication could have been a simple pile of stones, cave paintings, clay tablets or paper. This topic will exam Digital Media.

Digital media is the use of information and software technologies to communicate information. This information may be delivered by email, text message, mobile phone or podcast.

The Purpose of digital media

 

Most of you have been able to use a book to obtain information, learning and entertainment. The computer has enabled humans to add a new dimension to media called interactivity. Both these mediums or media are a way of communicating a message.

If you were able to navigate to this page, then you have been using the interactive features of the web browser. This interactivity allows you to control how and what you view.

Browsers are not the only computer technology that uses digital. Applications such as Microsoft office are digitalise formats. Animation, graphic, video and audio formats are greatly enhanced in the digital format.

Digitalisation allows faster processing and larger storage to occur and generally enhanced quality.

Digital media uses files that use 0’s and 1’s that the computer is able to interprete these 0’s and 1’s form a binary numerical code. This digital data uses software and hardware to provide a media that humans can understand. The message may be in a graphic, a video or a audio file format displayed using a device such as a monitor or speaker.

A vital part of a digital media product is that it delivers a message, to the intended audience. As we have seen previously, desktop publishing is essential, so that the product is capable of doing so by way of the appropriate page layout and design. The actual medium used to deliver the message needs to be correct as well. Text messaging is generally comprised of short abbreviated words for example great is written as “gr8”.

Writing Skill 1
Writing in a full sentence
Five Parts of a Complete Sentence

  1. Capital letter- A capital letter is always used at the start of a sentence, and also for Proper nouns.
  2. Subject-The subject is who or what the sentence is about.
  3. Predicate-The predicate is the verb or action that is being done.
  4. Complete thought-This is important as this makes the sentence logical. A noun, predicate and capitals can be used, but there needs to be a conclusion or logic.
  5. Terminal Punctuation- The terminal punctuation may be a full stop, question mark or exclamation mark, and one of these need to be used.

 

weekly homework task 1  (Due end of Week 2)
Q 1. Write in your own words the meaning of the word “media”
Q 2. What is meant by the term interactivity and list the benefits of interactivity to a message?
Q 3.Suggest how a digital media product could be assessed.

Types of Digital Media Devices

Today nearly every device that connects to a computer is a digital device. These include scanners, cameras, barcode readers, QR readers printers, phones and audio devices.

These devices handle data that has been encoded from analogue to digital values. The values are in binary form of “0”s and “1”s. Follow these links to see more about digital camera that captures images not on film but in a digital format that is stored and media center computer.

Types of digital media products

View the development in use with statistics on the use of Digital Media.

 View the development in use of Video.

Here we will examine three types of digital media products:

  • Graphic digital media and products
  • Audio digital media and products
  • Video and animation digital media and products

 

Graphic digital media and products

Two main digital media areas exist and for our study, one is Graphic Design the other is Desktop Publishing (DTP).

Graphic Design software provides a the user with the ability to manipulate or to create images. Photoshop, Sqirlz and Paint are examples of a graphics application. Graphic programs require an input device such as a mouse or tablet.
DTP software allows the user to create text with other formats such as graphics and audio. Microsoft Word and Publisher are examples of DTP applications. These two primarily work to create printed documents. Webpages are also examples of DTP and Microsoft SharePoint is an example of the application that could be used.

In general when inputting data into a graphic design media, use the highest possible quality formats. When the data is to be distributed on the Internet standard formats such as jpg and gif should be used. For Optical Discs the highest possible quality should be used such as TIFF or PNG. When storing your file, save it in a lossless format.


portfolio task 2

Use any three of the seven Event graphics. Use the following site. Add these three promotional items to your Google Site as portfolio task 2. See how to use Designer here watching the “getting Started Tube”.

 

weekly homework task 2 (Due end of Week 3)
Q 1. Name the most common digital media formats used on the Internet.
Q 2. What are the general rules for the input and output of graphic design.
Q 3.Suggest how a digital media product could be assessed?
Complete and post these three responses in your site on homework page.

Audio digital media and products

 

Audio data in a digital format is created by the process of data sampling. This process captures sounds and converts these analogue waves into digital. Audio is a very important component of a digital media product, as it provides background or reality sounds. Audio sequences initially comprised of MIDI files, however, advances in sequencing software has provided a means to mix sounds and to add effects.

The most common audio file types are MP3, WAV, MIDI, AAC and WMA. A quick google of these will provide you with simple explanations of each of these.

Video and animation digital media and products

Animation sequencing is more difficult to complete owing to the software that is currently available. Video sequencing though is much simpler, once again due to the available software which is much simpler to use. When a video camera is purchased it will always be delivered with an application that allows the editing of video. Windows Movie Maker is a program that may be used for many types of formats.

Video and animation may be distributed well in an optic disc format. The Internet is now a preferred distribution medium due to the availability of super fast Broadband, along with large storage and faster processing power provided by the personal computer. Telstra provides a movie download service to its clients, whereas before the client was required to go to a video store to rent a DVD.

The most common video and animation file types are MPEG-2, FLV, MOV and AVI. A quick google of these will provide you with simple explanations of each of these.

Data Types of digital media products

Data is raw material, “0”s and “1”s, that is given meaning by computer hardware and software. This data once processed is then called information. This information may be text, graphic, audio or video formats.

There are two forms of data, analogue and digital, analogue is from the natural world, for example your voice, colours or sounds. These waves vary in frequency. Digital data is when these frequencies are given a number value of either a “0” and “1”.

The smallest unit of data and memory is called a “bit”. These “bits” are combined in units of 8 bits, which are then known as a “byte”. So this is how a computer stores data on a computer.

Data is processed in an appropriate software, this is known as organising data. If you are creating data which has many numbers and or formulas, then you would use a spreadsheet application. A graphic would have the data created using a graphics application such as adobe Photoshop.

The main data types that you may be aware of are text, numbers, audio, video and animation and graphics. These would generally be processed with different applications as described above.

Data may be transmitted between computers in two main ways the first is serial data transmission and the other is parallel data transmission. Serial data transmission has each bit being transferred along a single path or bus which is slower than when data is transferred using the parallel data transmission, which has each bit using its own path or bus, so a byte is transferred at the same time. Parallel data transmission is faster though more expensive and restricted to a cable of a meter or two.

Data manipulation techniques

Technology has now given the ability to modify data in a way that was not possible even fifty years ago. Analogue data was able to be manipulated, however, by digitising data, that is to give a value to the data of either a “1” or a “0”, the manipulation is almost endless with the appropriate hardware and software.

Hardware allows the interaction to occur. The hardware has five functions, with different hardware carrying out a function. These five functions are input, output, storage, processing and control. The first three functions are quite evident allowing a user to input data and instructions, output data as information and to retain data on a storage device such as a hard drive.

Processing and modification of the data occurs in the processing and control functions. The data is processed in the central processing unit(CPU) according to the instructions on control of the data from the control function.

The exercises laid out below will give you the opportunity to manipulate data yourself.
The tubes below and the exercises demonstrate manipulation and the social effects of such manipulation. There are many types of manipulations which include rendering, morphing, tweening, cropping for graphics while cutting, filtering and sound special effects are used with audio.

Video and animations are often manipulated in similar ways to that of audio, with cutting unwanted segments, with compression techniques to reduce the size of the video. Another form of manipulation is carried out by timing controls, this is important as the time codes which are found in video formats control the start and finish of each segment.

Writing Skill 2
Proof reading
Proof reading is when you check what you have written makes sense.

  1. Read the document out loud- if you read something with your “mind” it will generally look fine. However, when you read it aloud, errors if they exist appear.
  2. Finger the text-Use your finger to follow the text as you read it. This slows down your reading and lets you check spelling and punctuation.
  3. Backward check-Start the check from the end of each paragraph. Read from the last sentence first, from the start of each sentence. This allows you to concentrate on the text not the content.
  4. Headings and subheadings- Read these to make sure they make sense.

Digitisation process of Data types

This process by a computer to convert analogue to digital is called digitising. The computer accomplishes this task through the use of a range of devices, a microphone collects the frequencies from your voice, measures the data and gives it a single digital value. A digital camera will carry out the same process with the shapes and colours that are captured when a picture is taken.

The computer reverses this digital process when we access the data as information. The voice that was captured by the computer hardwarew and software, is converted back to an analogue electrical current, by the sound card and then the speakers broadcast the sound of your voice.

Binary is the name that is given to the “0”s and “1”s, that the computer uses. As you may understand by now, that all data is therefore, stored and transmitted by electric currents, this is that the computer is formed by a huge number of “on” (“1”) and “off” (“0”) switches.

Optical Character Recognition (OCR) is a process where a hardcopy of text or images, may be digitised. Scanning uses light which uses mirrors and lenses to focus the text or image onto a micro chip, that detects change in the reflection. The scanner will generally create a bit mapped image of the text or image. Click here to see how OCR and Scanning works.

Factors affecting file size

The higher the sampling rate of audio digital media files the better the quality of the sound, but the file size is larger. The sampling rate measures how many sounds are made per second. An MP3 audio file will have a sampling rate of 44,100 samples per second. A voice recording will be only 22,050 samples per second.

Pixels are the measurement units used in an graphic digital media file. A high quality image that is 7-megapixels will have seven million pixels. As in audio, the better the quality the larger the file size.

Animation is measured differently. An animation is measured in frames per second. An AVI file originally having 30 FPS and 300,000 kb will after compression can be compressed to 42,000 kb. The advantage of this will be the transmission and storage will be more economical. The disadvantage is that the quality will be much worse.

File size in digital media products is an important consideration, as transmission, processing and storage demands increase with file size. Data compression is a process that reduces the size of a data file. Compression basically works by removing data which is duplicated, outside of the frequency range of colour and sounds that humans are able to recognise. There are two forms that we concern ourselves with, they are lossless compression which reduces file size, but does not delete the duplicated data for example. The other form of compression is lossy compression, which does delete permanently the data which is lost. The advantage is that lossy files are much smaller than lossless files.

Display and distribution

This site is using a number of streaming video to distribute information. Click here to see how streaming and audio works.

Digital media products will not always work on every computer that attempts to display it. Quite often plug-ins are required. An example of this incompatibility is found in different internet web browsers. Some browsers will not display java scripts that display fine on another browser.

User environments also need to be taken into consideration, is the user using a dial-up connection, this would inhibit streaming data significantly. Does the user have a special need that could make your product more accessible if modified to such a need.

It is very difficult, due to the advancement of technology to meet the same specifications of the end user of a digital media product. The technology that they are using may be older therefore, incompatable. Quite often though the addition of a link to additional plug-ins is worthwhile to provide users with access.

Distribution of digital media was once quite limiting, hard drives were small in capacity, removal storage was also restrictive, and certainly the low speeds of the internet did not provide for the distribution of digital media.

DVD and CD was and still remains an ideal way to distribute digital media. These have the capacity to deliver a high quality product without disruptive downloading issues. These had limitations in the amount of data that may be stored, and distribution costs were generally high. There was good control over ownership of the product though.

Fast Broadband has provided a cheap alternative to optical disc distribution. Digital media may be distributed easily and at a high quality now. The ability to update a product is an additional advantage of Broadband over optical discs.

Project development

 

The planning, production and overall development of a project has six steps.
The planning, production and overall development of a project has six steps.

 

  • understanding the problem
  • making decisions
  • designing solutions
  • implementing the solution by testing the product
  • implementing the solution by maintaining the product
  • implementing the solution by evaluating the product

 

If you do not know what is required to be completed to solve a problem, then the resultant solution is very unlikely to be correct. It is therefore, important that the task be understood. this may be done by asking questions of the potential participants of a solution.

Once that you decide upon the problem, then you need to decide on a solution. Probably thinking about one design only is not the best, create a few designs so that you can decide upon the best.

Once that you have decided upon a solution you may then commence to create a solution or product that will solve the problem. Make what is known as a prototype first. a prototype is a model or limited functioning product, to see if the solution is appropriate. a storyboard is also a sound design tool to develop a product, especially a video or audio product.

Once you have decided upon the solution, then make it. evaluation of the product is a continual process and should be completed through out the design and implementation process. maintainance will also be required to be carried out as the product is used.
